The 20th century saw air power transformed from novelists’ fantasy into stark reality. From string and canvas to precision weaponry and stealth, air power has progressed to become not only the weapon of first political choice, but often the only conceivable option. This rapid development has given rise to considerable debate and controversy with those holding entrenched views rarely slow to shout their case. Many myths have grown over the period, ranging from the once much vaunted ability of air power to win wars alone through to its impact as a coercive tool. This volume examines the theory and practice of air power from its earliest inception. The contributors have been drawn from academia and the military and represent some of the world’s leading proponents on the subject. All significant eras on air power employment are examined: some are evidently turning points, while others represent continuous development. Perhaps more importantly, the book highlights the areas that could be considered to be significant, and invites the reader to enter the debate as to whether it constitutes a continuum, a turning point, or indeed a revolution. The expert analysis in this volume will serve as a guide to past perceptions and will help to equip current analysts for the 21st century.
